HOW TO FIX:It's problem with columns/tables in database.1. In my post are two versions of acc. maker "..for TFS 0.3" and "..for TFS 0.2.x"2. If you use TFS 0.2.6 - 0.2.12 server/database use version "..for TFS 0.2.x"3. If you use TFS 0.3 server/database use version "..for TFS 0.3"Else you get this error. If you actualized your database from 0.2.x to 0.3 and get this error something is wrong in database.
